The 455 replaced the 425 for the '68 model year. There was no model year in which both were offered. The 425 was the largest engine from 1965 through 1967, with 455 the largest from '68 through '76. If the 98 you're looking at has it's original engine, it can only be a 455.

<br />Thanks I've always wanted a 425 and now this car popped up so I went online and saw a guy on the hamb talking about a 68 with a 425 so I had to run it through you guys... cant believe everything online,, funny because Joe P was on that very thread schooling people who there who were giving wrong info.<br /><br />oh well this 98 still looks appealing, ever since I got rid of the 63 f85 convert I told my self next convertible I get has to be a big car with a body on frame.<br /><br />Might pick this up. <br />I. Suppose that 1968 was a good year for the 455 right?<br />

i'm sure you mean the 425 was replaced by the 455 in 68,there is nothing wrong with a 425 tho,they are a great engine

I don't think there were any "bad" years for the 455. They were all good years. The latter year (mid-'70s) versions tend to be less desirable because they were detuned for emissions purposes. The '68 455s were the first ones and therefore probably among the more desirable.

I'm wondering what the big deal on this is, anyway. The car you're looking it is a luxury-barge land yacht. It will float down the road like a living room on wheels. It's a big, heavy car. It has the big engine for a reason. It's not a performance car. As long as the engine is in good tune and running well, be happy and enjoy the car. That's all anyone who purchased one back in 1968 did.

no big deal I want exactly what you described. Just asking those who owned one.

I second this suggestion. Try Safelilte or a local auto glass company. They may say no, but you'd be surprised what these companies can still come up with. I checked the Safelite website just now, and, while I didn't go all the way through the selection process because I don't actually have a car that needs glass, they do go back to 1968 when selecting the year, make, etc. of your car. Can't hurt to check.

Hi Kenneth: We called my 1984 98 Regency 4 door our "couch on wheels". My wife rode in the middle of the back seat with a kid on either side. That was a nice car and miss it. Regards, Trent in Los Angeles
